“Today was a good day for common-sense Republican leadership and a bad day for the Washington special interest groups that have tried to mislead the Republican grassroots,” LaTourette said.

Main Street Advocacy is the textbook definition of a Washington special interest group. The two largest donations so far this cycle to Defending Main Street, the group’s Super PAC, are $250,000 from International Union of Operating Engineers and $100,000 from Laborers International Union of North America.

How did Main Street Advocacy and its sister organizations beat “the Washington special interest groups that have tried to mislead the Republican grassroots” in last week’s primaries? By spending more than half a million dollars duping primary voters into believing big-government Republicans will fight for smaller government.

“Mainstream Republican primary voters have once again rejected groups like the Club for Growth and FreedomWorks, and their efforts to sell purity for profit,” LaTourette said on May 7 before concluding, “Voters aren’t buying the snake oil that these special interest groups are selling anymore.”

LaTourette, a K Street lobbyist, is certainly concerned about profit — the profit he stands to lose if Americans elect more legislators who are serious about reining in the $17.4 trillion national debt and beating back the relentless growth of the federal government.

However, LaTourette’s schizophrenic song and dance has long involved attacking the “extreme right” and calling conservatives “crazy” in one breath, and then bemoaning conservatives’ lack of partisan unity in the next.

“The Club for Growth is a cancer on the Republican Party that prides itself on supporting rigid, divisive and obstructionist candidates,” LaTourette said last July.

Calling opponents a cancer and accusing them of being divisive in the same sentence. Pure LaTourette.

LaTourette often speaks of the need for “pragmatism” and “common-sense” leadership as represented by Main Street Partnership, which also happens to be led by LaTourette.

On health policy, Main Street Partnership believes “that the provisions of Obamacare that are not working should be repealed” but that “those provisions that are working should be retained.”
